Twilight's eyes snapped open. She tried to move, but her wrists were stuck. She turned to the side. Cadance was there, the real one. They hadn't restrained Cadance, but since she was in the middle of laying eggs instead of escaping, it seemed they didn't need to.

The queen smiled. “I suppose I can introduce myself, since you are about to have your mind shattered anyway.” The queen bowed. “I am Chrysalis, queen of the changelings. Remember it carefully. Before long you won't have a lot of things left in your head, and the name of your new mistress should be important.”

The Foreplay

The cave was huge. Crystalline structures and tunnels stretched as far as the eye could see. Twilight glanced around. Aside from some scuffing on her clothes and a slightly strained ankle, she appeared to be fine. Whatever teleportation spell Cadance had used, she couldn't tell where she had landed.

“Enjoying the view?”

The voice was definitely Cadance's. It was impossible to tell where it was coming from.

“Show yourself!” Twilight shouted.

Cadance laughed. “If you insist.” Lights flashed through the cave, and a picture of Cadance's face appeared on one of the larger crystals. “Do you like the view? These caves are quite far beneath Canterlot. I believe some unicorns tried mining here or something a long time ago.”

“Do you expect some silly caves to stop me? I'll get out of here, and I'll expose you to everypony else!”

Cadance laughed again. It sounded like ground glass, short and rough. “Oh, wander around all you like. You'll never escape in time to rescue your brother.”

“You leave my brother alone, you witch!”

“Oh, and feel free to say hi to the real Cadance while you're down there. I imagine she could use some company.” The picture faded, though a faint chortle echoed through the cave.

The real Cadance? Twilight thought. Whatever that meant, it certainly didn't sound good.

She froze. She had definitely heard something. Sharp, heavy breathing.

Twilight tried to follow the noise. It sounded close, but it was hard to tell in the echo-laden cavern.

She turned a corner. Her hand reflexively covered her mouth in disgust. It certainly looked like Cadance—same hairstyle and body and face. Her pink dress also looked similar despite the layer of dirt coating it.

That was where the similarities stopped. Cadance was bound to one of the large crystal walls, her wrists glued to it by some green liquid. More of the stuff covered her mouth, and strands of it stood out sharply against the pink of her hair.

Her dress was torn. Her breasts and stomach were exposed, and her belly bulged outward, just enough to be noticeable.

Twilight rushed over to her. “Cadance. By Celestia, what did that impostor do to you?”

Cadance didn't answer. Her eyes were closed, her head rested loosely against the crystal.

Twilight tore off a piece of her skirt. The goop didn't seem that dangerous, but it was best not to take chances. She certainly didn't want to use a spell to burn it off that close to Cadance's face.

She wrapped her hand in the strip of cloth, brought it up to Cadance's mouth. The gunk, whatever it was, was warm and sticky. She managed to pry it off, and tossed the soaked rag aside.

“Cadance?”

Cadance opened her eyes. They seemed dull, glazed over. Her mouth hung open, and for a moment it looked like she was trying to say something.

“Cadance, it's me, Twilight.”

Cadance's mouth moved again. Her words were barely audible even in the silence of the cave. “Twi-light?”

“Come on, we have to get you out of here. Especially before that impostor does whatever she's planning for Shining.”

“Shi-ning?” Cadance whispered.

Twilight freed Cadance's wrists easily. She slumped further down, her arms falling limply to her sides.

Twilight hooked Cadance's arm over her shoulders. Getting a grip on Cadance's waist was a little tricky, but despite the height difference she managed to pull both of them to their feet.

Cadance's legs wobbled, her mouth still hung open. Whatever they had done to her had taken its toll. Definitely too risky to levitate or teleport her in this condition.

Twilight took a step forward and Cadance matched it, just barely.

“It'll be okay, Cadance. We'll get out of here and expose that impostor. Then we can get you some medical treatment or something.”

Cadance's mouth moved, but no words came out.

It was slow. Every step took ages. It was probably impressive that Cadance's legs worked at all, but that didn't make it any less frustrating. There was no telling how long she had been down here, and Twilight tried to be gentle. The thought of that monster alone with her brother kept sneaking up on her, however, making her take larger steps than she should have.

Finally, an intersection came into view.

“Well, it's a start, I guess,” Twilight muttered. “Maybe I can cast a mapping spell or something and—”

Cadance dropped to her knees, dragging Twilight with her.

“Cadance? What's wrong? Did you—”

Cadance's mouth moved again.

“Cadance? What did you say?”

“Egg,” Cadance whispered.

Egg? Before Twilight could puzzle out what that meant, Cadance bent her legs, took her arm off Twilight.

The sound was not loud, but it didn't need to be. It filled the cave with slurping and squelching and the wet echoes were impossible not to hear.

Cadance moaned, planted her hands on the cavern floor. There was a wet, heavy thunk.

Twilight reached forward, slowly, gingerly. It was tempting to ignore whatever had just happened. She had to know, though. Medical procedure demanded she know as much as possible, and her disgust couldn’t override her common sense. If they were going to fix it later, she had to look.

She moved Cadance's dress aside. The slits in its side had become exaggerated after so much damage, and it did not resist.

She clamped her hand to her mouth again. More of the green slime was dripping out of Cadance's vagina and butt. A dark green egg sat on the cave floor, a pool of the gunk already hardening around it.

“By... By Celestia.” Twilight had to fight the urge to vomit. “What did that monster do to you?”

“Egg.” Cadance's words were still barely audible. She moaned again. Twilight jerked her hand back, moved a few steps backward.

The dress fell across Cadance’s back, and Twilight couldn't bring herself to move it back. She got a full view as another egg poked out of her former babysitter.

First it was mostly slime. It fell out of Cadance like a slow faucet, dripped down her legs, then onto her dress. Finally, it splattered onto the first egg, more drops following after.

The dark green of the egg showed up quickly. Pressing aside Cadance's flesh as it pushed out of her. Cadance moaned again, and the dark orb fell out of her, landing next to the first one with another wet thunk.

Twilight forced herself to inch back towards Cadance. She had to help her. Whatever that imposter had done to her, this only reinforced how important escape was.

Twilight picked up Cadance again. She tried as hard as possible to keep her hand away from any particular area, but as they shuffled forward it was hard not to touch Cadance's skin now and then. The tears in her dress made it impossible to avoid.

“Don't...don't worry Cadance. We'll get out of here and Celestia will be able to fix you just fine. I'm...I'm sure the Canterlot doctors have dealt with worse things.”

They moved forward. It was a simple spell to make a compass or to locate places, so Twilight knew they wouldn't get lost. Then Cadance slumped to her knees again, whispered that word.

She kept laying eggs, over and over again. Twilight didn't bother to time it, or to count the eggs. It almost seemed like the frequency increased the more it happened. Part of her said that such information would be useful later for treating her condition, but the thought didn't help. She didn't even look each time Cadance did it, preferring to glance at a wall.

Finally, after what felt like hours, they arrived at a larger cavern. The crystals provided some light, but it was still a very dark place.

“Don't worry, Cadance. My spell says we're getting closer. We should emerge near the castle, then somebody can help us alert the princesses—”

Twilight froze. She had definitely heard something. Scraping or clicking or something like that.

“What was that?” she whispered.

“Eggs.” Cadance didn't kneel down.

Twilight tried to focus. Maybe that impostor had put something down here to guard them. It would only make sense. Her eyes began to glow and an orb of light bloomed in front of her. She grabbed it and threw it upwards, and it silently stuck to the ceiling.

She scanned the room. It was not as big as she had thought, but there were still plenty of branching tunnels that a guard might hide in.

Click.

“Show yourself!” Twilight shouted.

A shadow shifted in one of the tunnels. She focused again, maybe a weak fire spell would scare it off, since the candle spell hadn't.

Another shadow, in a different tunnel. Twilight raised her arm. Her eyes began to glow again, and red light started to spill out of her palm.

Finally, the creature stepped into the light. Though perhaps “skittered” would have been a better word; it crawled on all fours, each step making another soft click.

It looked like a regular person, or at least it had the body shape of one. No taller than a teenager, but it was proportioned just like an adult. The breasts and hips were certainly a testament to that. Its skin was solid black, but it didn't look like normal skin. It was slightly shiny, and Twilight could see the light from both her spells reflected in it. It looked up at her, and its teal, pupil-less eyes unnerved her immediately.

The creature stood up, and a penis dangled between its legs.

“Just what are you? Did that impostor put you here to guard us?”

The thing shook its head. “Oh, no. I'm still too young to guard anything. The guards are behind you.”

Twilight spun around, pushed her hand forward. The spell shot forward and charred the wall. There was nothing there.

Twilight turned back to the creature. More had joined it. They all looked the same, though their heights varied slightly.

She charged another spell. “So you are the guards then.”

The one in the center smiled. Its mouth didn't have quite enough teeth. “Oh no,” it said.

“We're just stalling,” said another.

“The queen wanted to be here when you were defeated,” said the third.

Twilight fired her spell, and the creatures scattered. If it hit any of them, they didn't react to the pain.

“Cadance, I need you to stay behind me. There's no telling what these things—”

Twilight's sentence was cut off by another moan. Cadance had hunched over again, and the squelch of eggs echoed through the cave.

“Mmm, I never get tired of that sound.”

Twilight turned around. Cadance's doppelganger stood at one of the tunnels, her mouth curled up in a smile.

The impostor licked her lips. “I see you found the real Cadance. Did you two have a nice chat?”

Twilight fired the spell. A flash of purple and red and green lit the cave, but it faded quickly.

The fake Cadance was unharmed. Her cocky, hip-tilted pose hadn't moved an inch. “Was that all?”

“How did you block that?”

“Well, I have been feeding on your brother for quite a while now. Some little girl isn't going to be able to beat me with a simple fire spell.” She laughed. “You know, after all those stories about what a magical prodigy you are, I'm rather disappointed.”

Twilight began to charge another spell. She screamed. One of the smaller creatures had leapt onto her arm, dug its teeth into her bicep. She drew her hand back, tried to remember what Shining had taught her about punching, but another latched onto her other arm, dragged it down with its weight.

The fake Cadance strolled toward her. She licked her lips. “Mmm.” She unbuttoned her dress. “I love it when they struggle.”

Another one of the creatures had clamped onto each of Twilight's legs, and another was scurrying onto her back. Every time she tried to charge a spell, one of them would pinch or scratch or bite her and break her concentration.

“You...you won't get away with this.”

“Oh, but Twilight, I already have.” The doppelganger slipped off her dress, kicked off her shoes. The pink of the clothing stood out so sharply in the cavern. “The only person who suspected me is stuck in this cavern, alone.” Cadance leaned down. She hadn't been wearing any undergarments, and her white skin was even more visible than her clothing. “Why, I could do whatever I like to you. Just like with Cadance over there.”

“They'll come looking for me.”

“They might. But I doubt it.” Fake-Cadance's skin glowed. It was like watching paper soak in water, opacity slowly spreading across her features, a subtle bit of green sitting at the edges of the transformation. In moments, her skin was the same black as the smaller creatures. Unlike them, she had a vagina instead of a penis, and her eyes had distinct pupils and sclera. “Why, they'll never know you're gone.”

The queen's eyes glowed green. Twilight tried to turn away, but the creature on her back grabbed her head. Its claws dug into her temples, wrenched her head back into place.

The queen grabbed Twilight's chin. “Now sleep.”

The Main Event

Twilight's eyes snapped open. She tried to move, but her wrists were stuck. She turned to the side. Cadance was there, the real Cadance. They hadn't reattached her to the wall, but since she was in the middle of laying eggs instead of escaping, it seemed they didn't need to.

“Wakey wakey, Twilight.”

Twilight tried to summon an insult, but her mouth was coated in the same slime she had ripped off of Cadance.

The queen smiled. “I suppose I can introduce myself, since you are about to have your mind shattered anyway.” The queen bowed. Her black skin reflected the light of the crystals, and the patterns shifted slightly as she bent down and up again. “I am Chrysalis, queen of the changelings. Remember it carefully. Before long you won't have a lot of things left in your head, and the name of your new mistress should be important.”

“Mfhfhuhsf!” Twilight's words were too muffled, but the tone was hopefully clear enough.

“Tsk tsk, so vulgar. I suppose we should skip straight to the training then.” Chrysalis knelt down, pushed aside Twilight's skirt.

Twilight tried to protest. A kick might've helped, but her legs had more of that goo plastered on them.

Chrysalis' mouth met Twilight's pussy. Twilight tried to scream, but the gunk was too viscous. All she managed to do was force some of it down her throat.

It felt so wet, so sticky. The tongue was too long, it pressed deeper into her, deeper than should've been possible. She screamed again, but it was just as ineffectual as the first.

Chrysalis withdrew, licked her lips. That same green slime ran down her chin. “Mmm, delicious. You taste like a virgin.”

“Fhmfyu, fyubiff!”

“There’s no need to make this unpleasant, you know.” Chrysalis knelt down. “Cadance resisted, and look where it got her.” She ran a hand through Twilight’s hair. “I’ve been feeding on your brother for quite some time now. I have so much magical energy at my disposal. I could make this the most mind-blowing experience of your life, if you let me. You’re going to be my slave either way, so why not enjoy yourself?” She leaned forward. Her lips brushed against Twilight’s. “You only have one decision left to make, after all. Why not spend your last moments of free will choosing pleasure?”

Chrysalis fell backward. The thunk of Twilight's forehead striking hers was loud enough to echo in the cave. The changelings littering the walls and ceiling buzzed collectively. A few swooped down to check on their queen, a few others landed next to Twilight.

Chrysalis sat up. She reached up to her forehead, and the red tint of blood was barely visible in the low light of the cave. “So that is how it is going to be.”

She stood up. Green light fizzled across her forehead as the cut healed. “Since you are committed to doing this the hard way, I may as well try out something new.”

Chrysalis’ fingers pressed into Twilight’s mouth. Twilight gagged as the goo pushed down her throat. It had no taste, but it felt so bloated, so puffy. It felt like the finger and goo together would suffocate her. Her eyes teared up, her throat bulged, she choked and gagged and the finger pressed deeper into her.

Then it stopped. Chrysalis’ finger withdrew, and Twilight felt air brush against her mouth and throat. She tried to say something, but her mouth did not move. Her tongue was glued in place. The gunk flexed across her teeth and gums and her jaw immediately started to ache.

“That should keep your mouth open. After all, we need to make sure you are compliant during the...procedure.” Chrysalis gestured at a pair of drones. “Hold her head in place. We don’t want another ill-conceived headbutt, after all.”

Claws dug into Twilight’s cheeks and temples. Not deep enough to draw blood, but they certainly hurt.

Her eyes widened. Green flame flickered across Chrysalis’ crotch, and when it faded a huge penis and matching testicles poked out of her groin.

Twilight tried to move her head, but the drone’s claws dug into her skin. She tried to force her mouth shut, but the goo had hardened. A bit of it flaked down her throat, but her mouth didn’t close.

“I would tell you to hold still, but, well, orders don’t have quite the same flavor when you don’t have a choice.” Chrysalis wove her fingers into Twilight's hair. It wasn’t necessary—between the drones and the goo, Twilight couldn’t move her head if she wanted to.

“I just love the little bit of motion when someone’s head moves.” Chrysalis ran a finger along her dick. “I’m not sure why. The way someone’s hair tugs on my fingers is so ineffectual. And yet, the little bit of struggle just makes you taste so much better.”

Chrysalis’ dick had hardened during her little speech. She moved closer to Twilight, and her dick nearly brushed against Twilight’s face. Twilight squirmed, and claws dug into her cheek. Her hair strained against Chrysalis’ fingers, just enough to hurt.

“Mmm, there it is.” Chrysalis shoved her dick into Twilight’s mouth. Twilight tried to gag, but couldn’t. Her mouth was still locked in place. There was no smell or taste, and the feeling of it was dulled by the shell of goo in her throat. Yet it was still unmistakably there, pressing against her throat and lips.

It twitched, squirmed for just a moment, then a stream of something shot out of it and into Twilight's throat.

This new substance wasn’t the same as the goo. It was more liquid and runny, and it had a taste. It tasted awful, like gelatin and sweat.

Chrysalis moved her hips back and pushed them forward again. “Now technically, I don’t have orgasms or anything that silly. But I must admit the motions are still nice. They add a little suspense.”

She thrust in and out again, and her dick dragged along Twilight’s throat. It still felt too big, like it shouldn’t be able to fit in Twilight's mouth. The motion made the stream of liquid ripple slightly, and it pooled at the back of her throat. She tried to gag; the taste and motion and weight made her feel like she was going to vomit. The goo around Chrysalis’ dick stayed in place, and she felt her cheeks swell with the liquid.

The claws on her temples shifted down a little, planted themselves on her cheeks and pushed down. Her throat clogged up again, the dick still leaking more of the stuff into her mouth.

She felt the liquid hit her stomach, collect inside her body. It felt like eating warm soup, only it made her feel disgusting instead of content. The stream continued. As more and more of it poured into her, she felt her stomach start to bulge slightly. It kept filling, kept stretching, and she felt her belly strain at her blouse.

Chrysalis finally pulled out, and Twilight’s coughs echoed throughout the cave. Green gunk splattered across her shirt and onto the cave floor.

Chrysalis laughed. “How did it taste?”

“What, what did you do to me!” Twilight flexed her jaw. The shell of goo had softened, and she could feel her teeth and tongue shift. She opened her mouth, tried to think of an insult. She coughed again, more goo leaked out of her and onto her chin. The taste wouldn’t leave her tongue, her jaw still felt sore.

“Just something to help you relax.”

“No, I won’t...” Twilight coughed again. What was I about to say?

Chrysalis pulled Twilight’s hair backward, wrenching her eyes towards Chrysalis’. “Now, I asked you a question, Twilight. How did it taste?”

Twilight tried to process the question. The insult she had been trying to think of faded completely, and no other thoughts showed up to replace it. Her jaw moved a little, but no words came out.

“The phrase you are looking for is ‘wonderful, my queen’.”

“Wonderful, my queen,” Twilight whispered. No, that couldn’t be right. She had meant to say something else.

“Good.” Chrysalis released Twilight’s hair. “Now that we know you are docile, we can cut you free and get to the fun part.”

Say something. Twilight told herself. The thought just sat there, alone. Her mouth moved, but the only thing that came out of it was another dribble of green slime.

The goo around her wrists dissolved, and Twilight felt her arms fall limply to her sides. Magic. She needed her arms to do magic, and they had just freed her. She knew dozens of spells. Hundreds. Yet she couldn’t think of a single one.

The goo around her ankles dissolved, and her legs fell to the sides slightly.

“Now, take off your clothes.” Chrysalis leaned down. “We wouldn’t want them to get messy.”

Twilight’s arm suddenly latched onto her shirt buttons. That’s, that can’t be right. Her arms had been completely limp a moment ago. Her fingers fumbled with the buttons, but finally the first one unclipped. She leaned back against the rock. It hadn’t been this difficult to put her shirt on, had it? Chrysalis must have done something to her. Another button came loose, andshe felt her stomach strain at the fabric. It felt nice to have that pressure off of it.

She had chosen a shirt with far too many buttons. It felt horrible wearing it, but they just would not come undone any faster.

Finally, her overshirt came off. Then her undershirt, that was easier. Then her bra. It felt nice, the cool cave air on her swollen stomach. Much better than those heavy clothes.

“Now your skirt and leggings.”

“No,” Twilight whispered. She definitely needed those. The shirt wasn’t important, but taking off everything else was a bad idea. Something told her that.

Chrysalis laughed again. It sounded like a bird being eaten by a cat. “And why not?”

“I...I don’t know,” Twilight whispered. It was so hard to argue with Chrysalis. Why did I call her a witch earlier?

“You must be tired.” Chrysalis snapped her fingers, and three drones flocked to her side. “Let me help you.” The drones moved forward at the same time, pulling off Twilight's shoes and socks and leggings and skirt, moving slowly and carefully.

Chrysalis smiled. “You look quite attractive, for a human. I suppose Celestia has good taste after all.”

Twilight's body still wouldn’t move. It suddenly felt so cold in the cave. Why had she taken off her clothes?

“I’ve been thinking about this for a while, you know,” Chrysalis said. “All the magic I’ve siphoned off your brother and Cadance has just been sitting in my body, begging to be released and used on something.” She knelt down, ran a hand along Twilight’s shoulder. “The invasion will be so incredible. Thousands of people to enslave and break and mold however I like. I had to do it so slowly with Cadance. I had to savor it, take it easy. Reserve my magic by doing it the old-fashioned way.”

Twilight couldn’t think of anything. So many of those words sounded bad, like they deserved a reaction. But her body still wouldn’t move. Her thoughts were so slow.

“But you, I can do something ridiculous on, something fast.” Chrysalis bit her lip. “I have so many different ideas. So much magic to use. But, I suppose I will have to restrain myself. After all, you still need to be recognizable and lucid for the rehearsal dinner later.” Chrysalis stood up. “Or at least, close enough.”

Chrysalis moved her dick in front of Twilight’s face. “Now get in. The suspense is killing me.”

Twilight didn’t move. She wanted to comply, but the order made no sense. She blinked, slowly, her jaw waggled, but she couldn’t think of anything else to do.

Chrysalis grabbed her head, pushed her forward. Her face met Chrysalis’ dick, but it didn’t go into her mouth. It pressed into her nose.

Green light washed across the cave. Chrysalis’ dick shifted, rippled, and Twilight's face pushed into it again.

Get in. It still made no sense.

Twilight tried to say something, ask what Chrysalis meant, but her mouth passed across the opening. She could feel Chrysalis’ flesh sliding across her cheeks and chin and neck, but her brain was still moving so slowly. The situation seemed so absurd.

The cock flesh met her shoulders and kept going. She tried to breathe, but it was so damp and wet that her nostrils clogged up. It smelled like the goo had tasted, gelatinous and sweaty.

Her butt started to lift off the ground. She felt the pricks of drone claws lifting her up, digging into her legs.

Gravity forced her deeper into Chrysalis’ cock. She felt the moistness press onto her breasts. She slid more, and she reflexively sucked in her chest as the wall of wetness passed across her nipples and towards her stomach.

Her arms were pinned to her sides. She tried to breathe again, but only got another mouthful of slime down her throat. It tasted disgusting. Why had she said it tasted wonderful earlier?

Claws dug into her legs and thighs, forced her further forward. Her head popped into a slightly wider space, but the slime still pressed onto her face in the most disgusting way, impeded her breathing.

Her arms slid into Chrysalis, the warmth and sludge running across her elbows and forearms. She was dimly aware of something damp near her belly button, of how cold her legs and groin felt. At least her torso was warm.

No, I don’t want to be in here. The thought hit her like lightning. Oh no.

She tried to scream, but a glob of green goo stopped her before she started. “Chrysalis! W-what are you doing!?”

Chrysalis laughed, and Twilight felt the rumble of it all along her body. “Oh dear, I suppose I didn’t give you a big enough dose to dull your thoughts the whole time. How forgetful I can be.” Every word vibrated along Twilight’s skin. The multi-syllabic ones made her heart skip.

“Don’t worry,” Chrysalis said. “We almost have you all the way in.” Claws dug into Twilight’s ass, and she gasped as soft, damp flesh pressed across her hips and vagina.

“And once you’re all the way in, the magic will work quite quickly. You’ll barely have to marinate at all before the transformation starts.”

Twilight couldn’t breathe. Her breasts popped free of the shaft, but they were still cramped.The pressure and lack of air and the idea of what might happen made her panic. Her breathing quickened, and more of the slime dragged into her nostrils and lungs and throat.

“You, you won’t get away with this.” Twilight could barely whisper. She felt her hair stick together, felt her legs glued together. She tried to kick or struggle, but her ankles were already sliding into Chrysalis’ body.

Chrysalis laughed again. It was louder, more forceful. The pressure of it made Twilight’s head hurt. “Whatever platitudes you have to use, Twilight.” She licked her lips, and Twilight could feel and hear the motion echo almost as loud as the words. “That misplaced optimism certainly adds a bit of flavor.”

Twilight’s torso lurched forward, her legs slid down, and she crumpled into a fetal position. It was cramped and wet and warm. A little pool of that green liquid sloshed at the bottom of the sack, and the walls had a dull green tint. Twilight pushed up, and she could feel her hands rest on the cave floor through goo and skin. She tried to press her foot back, stretch it open or something. Her foot met the slick flesh of Chrysalis’ sack and stretched it for a moment. Then her hand slipped and she fell over.

“Struggle all you like Twilight. The transformation will start soon, regardless.”

Twilight tried to charge a spell. She felt the magic gather for just a moment before pain shot through her stomach. The drugged slime in her stomach pulsed, and she could see green light leak through her skin.

Finding purchase was impossible. The sack was too slick. Twilight kept crashing into her own legs as she slid around. Her breathing hastened. The smell was disgusting, and there was no way to escape from it.

Another pang shot through her stomach and she felt bile gather at the back of her throat. She vomited, and the green puddle that shot out of her matched everything else perfectly.

The sack lurched, Chrysalis’ body rotated and reclined. “Just enjoy yourself, Twilight,” she said. “I’d say it won’t hurt, but I’m honestly not sure. I’ve never done this before.”

Twilight clutched her stomach. It churned violently, and she could taste more bile at the back of her throat, more sweat and gelatin and salt leak into her hair and nose.

Her arm slipped. Her body felt so limp. Even worse than when Chrysalis had drugged her. Every muscle and pore and nerve felt like it had been turned into jelly.

She tried to stand up, get into some position that wasn’t resting in a puddle of spunk. Her hand pressed against the cave floor again, but something didn’t feel right. When she pulled her hand up, the goo clung to it. She tried to wipe it off, and her palm felt so spongy.

Oh no.

She vomited again. Her thoughts didn’t work quickly, but they didn’t need to. Her head felt so light. She vomited again, and her stomach shrunk, her chest sagged, her legs crumpled.

She slumped onto her back. The puddle had risen. Before it had just covered her hand, now her hair and back and navel were swamped by it.

She felt something leak out of her vagina. It almost felt nice for a moment, but then more green slime fell out of her nose and mouth.

She brought her hand up. It might have been the dim glow of Chrysalis’ body, but it almost looked opaque. Like a piece of cardboard that had been soaked in water. The green slime and her skin blurred together.

She was still leaking. It had started to come out of her nipples and ass now. She opened her mouth to scream or protest, but all that came out was a dull gurgle and another dribble of green ooze.

She looked down. Her legs had been pushing against everything, but now they weren’t. She brought her leg up, and her foot was missing. When did that happen?

There was simply a round lump where her ankle was, more translucent sludge dripping off of it. She let it fall down, and she could feel the puddle cling to her skin. It felt nice. Calming. She coughed, and more liquid squirted out of all her orifices, drizzled out of her eyes and ears and nose.

She closed her eyes, let her arms fall to her sides. They sunk into the growing pool of green muck along with the rest of her body. She took a long, deep breath, She couldn’t tell if she was breathing air or drinking the slime. Perhaps it didn’t matter.

Her body deflated, she felt her head shift slightly. She took another long, slow breath. She dimly felt the walls of Chrysalis’ sack shrink slightly, bundle her together. This feels kind of nice. The color green overran her vision as the world melted and her thoughts ceased.

A gurgle leaked out of Chrysalis’ sack. Perhaps calling it that was a bit crude, but changelings didn’t really bother to name their own anatomy. She pulled her butt upwards, and her sack lurched and sloshed to match her movements. The cave rock did not make a good recliner.

“Finally. I thought that would never finish.” She pointed at two of the taller changelings, too lazy and sanguine to bother with telepathy. “You two. I’m going to give you the honor of helping Twilight leave my body.” She leaned forward, as best she could on the intolerable rock. “Don’t be gentle.”

The two of them rushed forward to fulfill the order. One of them wrapped its breasts around her cock, and the other began to massage her balls with one hand as it licked her shaft with the other.

It was unexciting. She had received thousands of orgasms from her drones, in every shape and combination possible, and there were no interesting events left anymore. Her body tensed, the drones built their pace, and there were no mistakes or surprises.

She neared climax, and forced herself to stand. She wrapped her hands around her shaft, pumped at it, then fell forward onto all fours. She kept pumping with one hand, her wingsbuzzing as she felt the liquid that used to be Twilight roiling inside her body.

She moaned and felt her hips thrust forward. Translucent, glowing goo shot out of her, coating the cave floor. The puddle spilt over and crept outward as more and more cum left her body. She could feel her balls shrink as the stream continued. The warm spunk washed over the cave floor, flowed onto her hands and feet and kept going. Eventually, the stream stopped and she stood up, her panting echoing slightly in the cave.

A smirk spread across her face as she telekinetically moved the pool of Twilight into place. She licked a few leftovers off her fingers as the spell charged. Still tastes like a virgin.

Green light washed across the cave. Exploded across it. A visible cloud of magic sunk into the puddle, and the liquid bubbled as the spell treated it.

The crowd of drones was silent. The occasional click or shuffle was quickly silenced. None of them dared disturb their queen’s moment of triumph, after all.

A loud, uneven gasp echoed the cave. The puddle shifted, and a little dimple appeared in the center of it. Parts of it rose up, flattened and tried again. Finally, an opaque green finger poked out of the surface. Another followed, and another. A hand pushed through, followed by an arm. Then another arm, and the top of a familiar, flat haircut.

Twilight planted her gooey hands on the cave floor as she pulled her body up and out of the puddle. She coughed again, and the green spit sunk right back into the rest of her body. Her breasts and torso and navel formed faster than her arms. By the time her legs coalesced, the puddle had vanished completely, forced itself into the right shape.

Twilight looked up. Her eyes and sclera looked off. Too transparent. Plus there was that green tint across everything.

“Hello, Twilight.”

“What...what happened to me?” Twilight whispered. Her voice sounded perfect.

Chrysalis smirked. “I broke your mind and turned you into my slave, remember?”

“Oh, right.” Twilight stood up. Her shape was perfect. She wobbled slightly, but she would adjust to her new body eventually. “Thank you, mistress.”

“Now, we have a rehearsal dinner to get to.” Chrysalis ran a hand through Twilight’s hair. It had individual strands, but it felt too slick. “Why don’t you concentrate a bit and solidify your skin. We can’t have any more suspicious people so close to my victory.”

Twilight closed her eyes. They scrunched together, and her skin slowly darkened, shifted colors, lost its green tint. Her eyes snapped open. “Is that better, mistress?”

“Perfect, you look just like your old self.” Chrysalis ran a finger across her new pet’s cheek. It felt just like real skin. Perhaps it was. Magic could do all sorts of things, and she had quite a lot of it. “When we get back to the castle, act natural.”

“Of course, mistress.” Twilight blinked, slowly and visibly. “I mean, Cadance.”

Chrysalis smiled. “Good girl.” She saw Twilight’s body shudder with pleasure at the compliment. It was almost enough to make her hard again. She would have plenty of time to test out the changes later, though. “Now get dressed. Have to seem normal. I should get changed myself.”

Author's Note

Because obviously the "Chrysalis captures Twilight" thing wasn't overdone enough already.
